BpLAZY1A Mediates Transcriptional Polarity and Drives Adaxial Tension Wood Like Tissue Formation in Silver Birch (Betula pendula) Branches

Sampo Muranen, Àngela Carrió-Seguí, Ema Marmara, Aleš Pěnčík, Juha Immanen, Ilhan Cem Duru, Mira Viljanen, Heikki Suhonen, Kirsi Svedström, Xueping Shi, Maja Ilievska, Pasi M. A. Rastas, Chang Su, Hanna Maarit Koivula, Juan Alonso‐Serra, , Ykä Helariutta

This paper identifies BpLAZY1A as a key gene regulating gravitropic signaling and tissue polarity in silver birch branches, linking gene expression asymmetry to biomechanical reinforcement and growth orientation.
